Cashion is known by NFL players, coaches, and fans for his signature first down call in which he would enthusiastically drawl "First dowwwwwn!" out to the crowd. In a 1997 interview with The Sporting News, he said, "I don't know of any time that started it or stopped it. It was just something that sort of evolved and been there ever since".[1] Cashion's promotion to referee came just one season after the NFL began equipping referees with wireless microphones to explain penalty calls and complex rulings to fans in the stadium, members of the media, and the television audience at home.

Cashion was inducteed into the Texas Sports Hall of Fame in 1999. He also provided the voice of the referee for several versions of the Madden NFLvideo game.
